Rexa, Inc.

- Model X2D-Series - Damper Drives



The REXA X2D Damper Drives allow for modulating duty cycle and precise positioning independent of load variation. Hydraulic pressure is generated by an internal positive displacement gear pump driven a stepper or servo motor with no limitations on starts, stops, or reverse cycles. This self-contained electro-hydraulic system locks the cylinder in place when no movement is required. This minimizes wear-and-tear on moving components and eliminates unnecessary power consumption.
